Tracking down the ancient headquarters of the Hidden Ones is one of the most rewarding pursuits in Assassin's Creed Valhalla. Scattered across England, these long-abandoned ruins contain unique armor pieces and crucial historical codex pages that shed light on the brotherhood's lore. Uncovering these secrets requires a keen eye for environmental clues and a willingness to explore forgotten spaces.

Discovering the Ratae and Londinium Bureaus

The Ratae Bureau is located just east of the Ledecestre town center, making it one of the earliest locations players will encounter. You need to look for a floor mural of the Assassin's Creed logo and shoot a hanging sack of stones to break the rubble below. Once inside, sliding under structural gaps will lead you directly to the legendary Hidden Ones' Gloves.

Further south, the Londinium Bureau is hidden just outside the eastern wall of the sprawling city of Lunden. Players must climb over a circular wall constructed of wooden posts to locate the secret entrance pool. Diving deep and navigating the flooded subterranean tunnels will grant access to the room housing the Hidden Ones' Mask.

Exploring Camulodunum and Eboracum

The Camulodunum Bureau rests underneath the historic city of Corcestre in the Essexe region. To locate the entry point, head to the southeastern corner of the ruins where a massive statue has toppled over. You will need to use a nearby explosive jar or an incinerating trap arrow to shatter the weakened floor segment.

Traveling north to Jorvik reveals the entrance to the Eboracum Bureau, situated just east of the main theater. Players must look for a hidden entrance leading down into the dark basement chambers of Roman ruins. Smashing nearby crates will reveal a crawl space that leads into a vast, gas-filled tunnel network containing the Hidden Ones' Robes.

Unlocking the Border Bureau Outposts

The Temple of Ceres Bureau can be found at the base of the mountains that border the western edge of Glowecestrescire. The entry sequence requires entering the crumbling temple steps and quickly neutralizing toxic gas using your torch. Successfully navigating these rooms rewards players with the defensive Hidden Ones' Leggings.

Finally, the Venta Belgarum Bureau is located on the far western edge of the fortified city of Wincestre. The entrance is accessed by jumping down into a deep well structure and swimming through a long underwater path. Moving a heavy storage rack allows you to return to the surface and claim the powerful Suttungr's Claw dagger.
